If anyone has the 2012.30 map file from an Indian bought nuvi, please remove the personal info from the file and post it on the forum as this one does not have Lane Assist info. Please post the jcv file also.

I suspect that this file also has Lane Assist info embedded in it, it's just not enabled. Is it possible to enable LA on this image, through hex editing the img file or something like that? If anyone has more info on this, please do share. Thanks.

I'm sorry, is my understanding of Lane assist wrong? What I see in your simulation are just turns, not the multiple arrows indicating the lane/s to use for the upcoming turn. Seen on highways in some of the images on the right of this page [Only registered and activated users can see links. ]

Also in the requirements tab for the India image it's mentioned "Please note, these full-version maps DO NOT contain premium content such as Lane Assist and Junction View. These features only are available on the preloaded maps within your device or through a specific update for the mapping region of your device."

Edit: Or have I completely misunderstood and you are just providing some data Catymag? Because I just can't imagine that you could be wrong about something regarding Garmin!

"Please note, these full-version maps DO NOT contain premium content such as Lane Assist and Junction View. These features only are available on the preloaded maps within your device or through a specific update for the mapping region of your device."

Correct, and for this particular CN you need the JCV files to also get Lane Assist in a JCV capable unit. With most CNs the LA info is embedded in the map file and the turn guidance arrow in the top LH corner of the map screen will also show the correct lane to take if the unit is capable of reading it, quite independent of a JV file.

Quite easy to get confused by Garmin's apparent ad hoc use of the terms: 'Junction View', 'Lane Assist' (sometimes 'Lane Info'), and Junction View with Lane Assist'. My (maybe incorrect) understanding of these terms is this: the first has Junction Views pics only, the second is usually obtained from LA info embedded in most CNs, and the third has JV & LA info in the *.jcv file so that when that file is used with a CN without 'premium content' will show both the junction views and the lane assist multiple arrows. Perhaps Caty or someone can either debunk or confirm this theory?
